Stephen Colbert and Neil deGrasse Tyson

In this eighty-four-minute video, Stephen Colbert (not doing his Colbert Report character) chats with Neil deGrasse Tyson. It's an intelligent, fun, and wide-ranging discussion, touching on science, history, and personal experiences of science. The most adorable parts: Colbert consults his phone for notes; and Tyson admits that the night sky reminds him of what he saw at the Hayden Planetarium as an eleven-year-old kid. There's a good forty minutes of Q&A, and both men are delightfully snappy dressers (check out the shoes boots on Tyson!).

To skip the preamble, zip forward to about six minutes in.

The original (non-YouTube) video is here. It's roughly the same as the YouTube version, except it buffers constantly. The discussion occurred at Montclair Kimberley Academy on 29 January 2010.
